Question: How did Apollo navigate?

Navigation. Apollo astronauts used three navigation systems to determine the proper flight paths to the Moon and back to Earth. An optical navigation system consisted of a scanning telescope and a sextant. With these instruments the astronauts could take star sights and plot the position of their spacecraft.

How did Apollo 13 navigate back to Earth?

All three took refuge in Aquarius and, abandoning Moon landing plans, looped around the Moon, using the LMs engine to speed their return to Earth instead of landing them on the lunar surface.

How did the Apollo guidance computer work?

The Apollo Guidance Computer in the command module had two main jobs. First, it computed the necessary course to the moon, calibrated by astronomical measurements that the astronauts made in flight, with a sextant not unlike that used by oceanic navigators.

How did the Apollo 11 land on the moon?

The Eagle lunar module had a descent rocket engine to slow it down, drop into a lower orbit and then hover over the surface. Guided by a landing radar, Armstrong piloted Eagle semi-manually using four clusters of rockets to finally touchdown in the Sea of Tranquillity on 20 July 1969.

How did Apollo get home?

After being sent to the Moon by the Saturn Vs third stage, the astronauts separated the spacecraft from it and traveled for three days until they entered lunar orbit. Armstrong and Aldrin then moved into Eagle and landed in the Sea of Tranquility on July 20.

Im Sam Lemonick and in this bonus episode of Stereo Chemistry, Ill be sharing the story of the science and serendipity behind that mostly unsung engine.

What programming language did Apollo use?

Did NASA use metric to get us to the Moon?

NASA has decided to use metric units for all operations on the lunar surface when it returns to the Moon. The Vision for Space Exploration calls for returning astronauts to the Moon by 2020 and eventually setting up a manned lunar outpost.

Why did NASA switch to metric?

Its performance was comparable to a first generation home computer from the late 1970s. By choosing to use SI, NASAs software engineers removed the need for the extra multiplication calculations that working with imperial units would have entailed.

Why didnt the US adopt metric?

The biggest reasons the U.S. hasnt adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.
